205 dnl per the autoconf manual, we can speed up autoconf somewhat by quoting
206 dnl the great gob of text. Thus it's not processed for possible expansion.
207 dnl Just make sure the brackets remain balanced.
209 dnl Since Emacs can't find matching pairs of quotes, boundaries are
210 dnl indicated by comments.
214 ### If you add support for a new configuration, add code to this
215 ### switch statement to recognize your configuration name and select
216 ### the appropriate operating system and machine description files.
218 ### You would hope that you could choose an m/*.h file pretty much
219 ### based on the machine portion of the configuration name, and an s-
220 ### file based on the operating system portion. However, it turns out
221 ### that each m/*.h file is pretty manufacturer-specific - for
222 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
223 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
224 ### machines. So we basically have to have a special case for each
225 ### configuration name.
227 ### As far as handling version numbers on operating systems is
228 ### concerned, make sure things will fail in a fixable way. If
229 ### /etc/MACHINES doesn't say anything about version numbers, be
230 ### prepared to handle anything reasonably. If version numbers
231 ### matter, be sure /etc/MACHINES says something about it.
233 ### Eric Raymond says we should accept strings like "sysvr4" to mean
234 ### "System V Release 4"; he writes, "The old convention encouraged
235 ### confusion between `system' and `release' levels'."
